InvokeWithException: make next successor a special begin node which has the same locationidentity as the invoke InvokeWithExceptionNode has the unpleasant property that it is a ControlSplit and MemoryCheckPoint at the same time. In terms of scheduling, a node cannot be placed after a ControlSplit node as it denotes the end of a block. Thus, instead of connecting a FloatingReadNode to the InvokeWithException node directly (as lastLocationAccess), we point rather to the BeginNode (non-exceptional case) or ExceptionBeginNode. To preserve consistency regarding memory dependencies, the former node must be also a MemoryCheckPoint.
